I've just come across a very nice comic in Chinese covering the arrest, interrogation, imprisonment and finally execution of three female prisoners in ten parts for a total of 232 pages. I can't read the Chinese text, but the narrative is pretty self-explanatory anyway. No idea who the artist is, or whether they have any more similar art.
Easiest way to post the link it to this search page on E-Hentai which gives all ten volumes:
With more than half a million absolutely free hentai doujinshi, manga, cosplay and CG galleries, E-Hentai Galleries is the world's largest free Hentai archive.
e-hentai.org
Here are a few example pages to give a flavour of the style of artwork -- highly realistic and detailed, reminding me somewhat of Feather (but better) or of
@settantuno -- indeed some of the settings would work pretty well with
@Praefectus Praetorio and his Singapore saga.
